摘要
利用积分回归法,分析了通化市水稻负泥虫的发生与气象因素的关系。并采用逐步回归方法,建立了水稻负泥虫发生量与气象因素的回归方程式,根据此方程式并利用当年的气象数据来预测当年虫害发生的轻重。
The relation between occurrence of Lema oryzae and meteorological factors in Tonghua City was analyzed. Using integral regression method,regression equation about the occurrence of Lema oryzae and meteorological factors were established.According to this equation and using meteorological data, the severity of pests could be predicted.
